Amazing features of Tgi3D SU PhotoScan:

High accuracy camera calibration and metrology software

Tgi3D Calibration and Metrology Tool is a separate executable in the Tgi3D SU PhotoScan package. Using this tool you can perform camera calibration and measurements over multiple cameras. Calibration tool comes with a simplified user interface to easily mark and edit correspondance points. You can set known coordinates to correspondance points, increasing acccuracy. Camera calibration tool has a preloaded camera database of thousands of cameras. It is also very easy to extend additional cameras/lenses into a local database. This tool is able to report measurement uncertainties accurately. Typically, when the user is satisfied with the measurement accuracy, the resulting calibration is exported to SketchUp.Watch Video
